Answer:
Option A
Step-by-step explanation:
We have y < 2x - 4 and y > 2x + 1.
=> 2x - 4 > 2x + 1
=> -4 > 1
Since this inequality is false for all real values of x, there is no solution for the system of inequalities.
Answer:
b) √200 = 10√2
Step-by-step explanation:
Here, the given expression is: √200
Simplifying the given expression, we get:
200 = 2 x 2 x 2 x 5 x 5
⇒ 200 = (2)² x (5) ² x 2
Taking ROOT both sides, we get:
Hence, √200 = 10√2
5x+4y=8
-5x from both sides, you get 4y=-5x+8
then you divide the equation by 4.
y=-5/4x+2
10x-4y=46
-10x from both sides and you get -4y=-10x+46
divide the whole equation by -4 and you get y=5/2x + -23/2 .
